A true Class A amplifier would certainly increase the resolution of one's electric bill.  I believe the initial target was early 2013. Lonnie made the quick comment in second to last podcast (I think) that we might even get them for Christmas. However, Emotiva has a lot of products in the hopper. Don't forget that the XPR-1 & 2 are due out next month, along with the UMC-200. Hang on a bit longer if you can. I have no doubt we'll see them soon, most likely in January or early February. Based on the preliminary specs, this amp should hit the sweet spot for many folks.  |

Will it gain some weight with bigger heatsinks? I don't mind trying to lift another 20 pounds if it helps with cooling.

Still waiting to hear a bit of info from Emo on this amp.

I wonder if they will be nice and give it to us at 29db gain?

I'm not sure how much of an improvement on Class A since Class A/B were already low in noise, THD and in fact they were not audible in hearing perception. Measurement can tell the difference but can your ears tell them? Can you hear the difference between .002% THD over .0002% THD?Low number below hearing range is just good on bragging rights.

No, its a statement on the quality and high competence of the overall design. Measurement numbers give you an idea of this quality without subjective bloviations and obfuscations.

But they don't tell you how the amp will sound. I want to know how it sounds, measurements can be played with and used in obfuscations as well. Which is why Emotiva has the 30 day trial I suppose.
This thread was started on Sept 1. 3 months later and it's as I suspected, it wasn't coming soon. At this point, with all of the new amps that have been released and Emo slaving away trying to get the 2 XMC's out, I'd guess we won't see this amp for a while yet.

I know that lots of people have strong feelings about how amps "sound", but I've never quite gotten it. If the AP data shows flat FR...... then it should perform with flat FR. I probably haven't listened to enough amps to really say much about "sound", but I've liked measurements..... Measurements don't lie, but how they "sound" seems to be more psychoacoustics... |

Very interesting! I wonder how these things might handle speakers that dip below 4 ohms for much of their frequency range, like, say, Thiel CS3.6s! The 4-ohm output and amount of Class A output is the same as my big pre-recession amp...
If this can't handle the Thiels, guess I'm waiting for the XPA-1XL!

I could have fleshed out my POV on this a little more, as all amps measure flat. But how they will perform the dynamic load that is a speaker is another thing. Speakers vary greatly from brand to brand in the load they present at different frequencies, and this is where I've found differences in amp performance. Then of course, Class A operation is superior to A/B, which is why Emotiva has decided to go in this direction. YMMV. |

Cool Sharkman, appreciate your comments.
I'll agree that no two speakers are the same, and I could easily imagine differences there with how the amps drive them.

Jim is right because even on same manufacturer but different series sound would be different.

30 watts of class A from Emotiva? I've got Klipsch La Scalas! Where do I get on the pre-order list?

30 watts of class A from Emotiva? I've got Klipsch La Scalas! Where do I get on the pre-order list? :-) As far as I know, Emotiva has not started a Pre-Order List for the XPA-1L just yet. You might want to check with Emotiva to see if they have started one or intend to start any time soon. Recently, Cathy has started Pre-Order Lists once the product is on the boat from China by placing the sign-up list on the Product Page for the item. As popular as the XPA-1L is likely to be Emotiva may start a list a littler earlier than usual. A phone call or e-mail to Cathy or Big Dan just might be all that is needed, assuming it is close to being released. Merry Christmas and Happy New Year. |

I sent an email last week and was told "sometime in 2013". I am eager, too. The XPR's look nice, but hey are overkill for my setup. And that 30 watts of class a has my really caught my attention.

Anyone have any wild ideas about pricing? Will this be a mono or stereo amp (the "1" in the name leads me to believe the former)? Any guesses about physical size? Since we're supposedly a month or less away from intro, maybe more info is available?

Since we're supposedly a month or less away from intro, maybe more info is available? Read this thread and ALL of those questions, and quite a few others, are answered. The amp won't be here for a while. Read the thread, It's informative an entertaining. |

Sorry - my dyslexia told me that there were 112 pages to the thread, not 12. I can read the 12. Thanks! OK - Thread read & digested. You're right; it answered my questions. Conclusion: XPA-1-L is not the amp for me. Why? 1. Power - My La Scalas are happy with <1 WPC. 10 watt output is earsplitting. I'll never use the 30 watts of Class A much less the Class A/B overhead. 2. Transistoritis - The XPA-1-L's power output transistors are voltage amplification devices. Tubes (current amplification devices) have proven to sound better with my speakers. 3. Cost - At ~ $1,400 per pair, there is some serious competition. The amps I currently have sound great, and the XPA-1-Ls would have to be truly exceptional to justify the additional expense. 4. Topology - The fact that the amps can automatically switch to Class A/B makes them indistinguishable (other that the amount of bias current) from any other Class A/B amp on the market. Yes, they're to be biased to offer the first 30 (or so) watts in Class A operation, but they're still basically Class A/B amps. If they were designed for true Class A operation only, I'd be more tempted. 5. History - I had an Emotiva XPA-2 (which runs for its first 10 watts or so in Class A). It did not sound dynamic with my high-efficiency speakers. Given that the XPA-1-L is yet another Emotiva Class A/B amplifier with Class A operation at its lower power outputs, why should I expect the new amp to sound different? 6. Curmudgeonliness - Self explanatory  Now having said all that, I'll probably still end up on the pre-order list...  |
